We present the case of a venous malformation (VM) masquerading as a schwannoma. VMs are thin-walled vascular dilations of various sizes that typically present as soft, compressible, blue masses that are associated with pain or dysesthesia. VMs are commonly found in the head and neck as well as the distal extremities. Notably, slow-flow VMs are hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging, and enhance markedly with contrast. However, VMs tend to be poorly circumscribed and fraught with venous lakes and phleboliths. Conservative therapy and sclerotherapy are the primary treatment options. In this case report, we present a VM presenting near the neurovascular bundle of the upper extremity axilla. Our case is unique in that the patient presented with symptoms and imaging qualities characteristic for a peripheral nerve schwannoma.
我们报告一例伪装成神经鞘瘤的静脉畸形（VM）病例。静脉畸形是各种大小的薄壁血管扩张，通常表现为柔软、可压缩的蓝色肿块，伴有疼痛或感觉异常。静脉畸形常见于头颈部以及远端肢体。值得注意的是，慢流型静脉畸形在T1加权成像上呈低信号，在T2加权成像上呈高信号，并在注射造影剂后显著强化。然而，静脉畸形往往边界不清，充满静脉湖和静脉石。保守治疗和硬化治疗是主要的治疗选择。在本病例报告中，我们展示了一例出现在上肢腋窝神经血管束附近的静脉畸形。我们的病例独特之处在于，患者表现出外周神经鞘瘤的症状和影像学特征。
